  The composition and sequence specificity of Pro-Ala-Lys-OH for the thrombolytic activities of P6A and related oligopeptides

  摘要：

  The in vitro and in vivo thrombolytic activities of Ala-Arg-Pro-Ala-Lys-OH, its analogs and the related peptides were assayed. The results indicate that when (5)Lys of Ala-Arg-Pro-Ala-Lys-OH is changed into (5)Arg, and (5)Lys of Pro-Ala-Lys-OH is changed into (3)Arg the thrombolytic activities are collapsed; when Pro-Ala-Lys-OH is changed into Ala-Pro-Lys-OH, and Ala-Arg-Pro-Ala-Lys-OH is changed into Ala-Arg-Ala-Pro-Lys-OH the thrombolytic activities are also collapsed; when (5)nLys of Ala-Arg-Pro-Ala-Lys-OH is changed into (5)nLeu the thrombolytic activities are again collapsed. All of the results indicate that for the thrombolytic activities of Ala-Arg-Pro-Ala-Lys-OH and the related peptides Pro-Ala-Lys-OH exhibits either amino acid composition specificity or sequence specificity. The composition and sequence specificity of Pro-Ala-Lys-OH reflects its rule as the pharmacophore of P6A and the related peptides. (C) 2004 Elsevier Ltd. All rights reserved.

  [1-(1 ',3 '-Dioxyl-4 ',4 ',5 ',5 '-tetramethyldihydroimidazol-2-yl)-phenyl-4-yl]oxyacetic acid (4), a nitronyl nitroxide, and its peptide derivatives, N-[1-(1 ',3 '-dioxyl-4 ',4 ',5 ',5 '-tetramethyldihydroimidazol-2-yl)-phenyl-4-yl]oxyacetyl-ARPAK (9a), -GRPAK (9b), and -QRPAK (9c), were synthesized and characterized. Judging from the results of electron spin resonance analysis, the newly synthesized nitronyl nitroxide containing peptides, 9a, 9b, and 9c, demonstrated the characteristics of free radicals. The free radical scavenging activities of 9a, 9b, and 9c were assessed using in vitro free radical scavenging tests. The thrombolysis effect of 9a, 9b, and 9c was evaluated using an euglobulin clot lysis test, a fibrinolytic lysis test, and in vivo thrombolysis tests. Results indicated that these nitronyl nitroxide containing peptides possessed both free radical scavenging activity and thrombolytic activity.

  We describe a novel class of beta-carboline alkaloid-peptide conjugates that possess both free radical scavenging and thrombolytic activity. These conjugates demonstrate therapeutic efficacy in a rat arterial thrombosis assay, as well as free radical scavenging capacity as evaluated in a PC12 cell survival assay. Our results indicate that beta-carboline alkaloid-peptide conjugate 26a exerts a significant protective effect against local and remote organ injury induced by limb I/R injury in the rat.

  Two kinds of linkers consisting of 3-(S)-1,2,3,4-tetrahydro-beta-carboline-3-carboxylic acid, ARPAK, GRPAK and QRPAK were synthesized. The thrombolytic activities in vivo indicated that the coupling position of 3-(S)-1,2,3,4-tetrahydro-beta-carboline-3-carboxylic acid in the peptides effected on the potencies significantly. When the C-terminal of the peptides was amidated by 3-(S)-1,2,3,4-tetrahydro-beta-carboline-3-carboxylic acid, the thrombolytic potency of the peptides was enhanced or kept. When the N-terminal of the peptides was acylated by 3-(S)-1,2,3,4-tetrahydro-beta-carboline-3-carboxylic acid, however, the thrombolytic effect of the peptides was banished. The expected specific beta II'-turn conformation and the stability to trypsin in the pseudopeptides with 3-(S)-1,2,3,4-tetrahydro-beta-carboline-3-carboxylic acid in its C-terminal may be responsible for the enhanced thrombolytic potency.
